Hi. You can also dry jewelweed-- I. capensis seems to work better this way than I. palida. That way you'll have it when you least expect to need it. For fresh plant or dried, I simmer the herb (a two-handed handful for fresh, a good palmful of dried) in about 2 quarts water for about 20 minutes, then cool & freeze the tea in cubes, but I also throw it in a spray bottle & keep it in the fridge, & it feels soooo good.

Its aggressive, but not really "invasive". I haven't grown intentionally, but it grows all over along the creek banks here. Have you popped the seed heads yet?

Sorry .. typo in subject line .. Impatiens capensis

Most people find these to be weeds. Seed is your best bet. I think that this species is native to your area as well. Maybe a native plant society sale. This is a very easy plant to grow just let the seeds set out over winter outside in the cold (they are hardy way up in to Canada)and they will come up.
